20.500.12556/RUL-175387 Hulled oat (Avena sativa var.Noni) and naked oat (Avena nuda var. Kamil) distribution of selected secondary metabolites during germination This study explores dynamic changes in growth, total phenolic content (TPC), antioxidant activity (AA), and phenolic composition during the germination of hulled and naked oat. The shoots and kernels of the germinated oat were analysed separately. Both TPC and AA increased throughout germination, particularly in the shoots with higher accumulation of the free phenolic fraction. LC–MS analysis of the oat extracts identified avenanthramides, isoschaftoside, vitexin, and phenolic acids as key metabolites. Avenanthramides, a major class of polyphenolic compounds in oats, varied in concentration and distribution between species. Germination notably increased isoschaftoside and vitexin levels by 28- and 5.3-fold, respectively. Differences in phenolic profiles indicate species-specific metabolic responses. To the best of our knowledge, this is the first comparative analysis of secondary metabolites in oat shoots and kernels during germination, providing new insights into growth dynamics and potential health benefits linked to elevated phenolics and antioxidant activity. naked oat germination isoschaftoside avenanthramides shoots kernels free and bound fractions oves Avena sativa kaljena ovsena semena frakcije fenolne spojine antioksidativna aktivnost sekundarni metaboliti true false true Angleški jezik Slovenski jezik Članek v reviji 2025-10-24 14:41:23 2025-10-24 14:41:27 2025-12-10 03:46:54 0000-00-00 00:00:00 2025 0 0 9 str. part 3, art. 145505 Vol. 492 Nov. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 633.13:581.142:66.094.3.097.8:547.56:604.4 0308-8146 10.1016/j.foodchem.2025.145505 241962755 zivkovic_1-s2.0-S0308814625027566-main.pdf zivkovic_1-s2.0-S0308814625027566-main.pdf 1 E7BF086BD9BEEF2C0A83A6B00CE84EAC 8b64e2a8a74c7340e68d3470e29fce38f317f14acb5826c0a6d384a3a6bb31b4 a0f34f8f-b0d6-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220915 https://www.sciencedirect.com/science/article/pii/S0308814625027566 1 78907101-b0d6-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220914 Biotehniška fakulteta 0 0 0
